About me, Contact
By iulian207My name is Berca Iulian, I am living in Leiden, The Netherlands, I followed the Politechnical University of Bucharest, Faculty of Electrical Engineering, discipline : Electric Motors.
I had my own CNC machine, and i was able to make several motor housings. Is a lot of work behind, much more that it seems.
I made many custom motor designs for different clients all around the globe, from: USA, Germany, Switzerland, Turkey, Poland, UK, Japan and many others, with power ranging from 10kW to 220kW.
For any inquire i can be contacted at iulian.berca@gmail.com
As a hobby i have built: electric cars , scooters, bicycles, go karts, quadcopter,rc airplanes etc…
I am very passionate about electric motor design, motor controllers, now i’m working to improve the brushless controller and i`m building brushless motors for: Light Airplanes, Large drones, Electric Scooters, Electric cars,boats, Pumps and many other applications.
The new motors i`m developing will bring high performance at a reasonable prices.
The motors are high performance type, due to high frequency capability of materials used, careful optimized core design, optimized winding design compared with what industry is using. By being able to design as i consider optimum, i can go in regions where big companies are behind do to old standards. In this way i will be always move faster than them, with years in advance.

Have a nice day, and remember: nothing is impossible, with enough effort.
Buna ziua,
Ai putea sa imi dai un pret pentru masina electrica Agila pe care ai facut-o?
As fi interest sa o cumpar.
Multumesc,
Ionel DINU
Salut.
Am vazut tocmai acum mesajul de pe site.
Daca mai esti interesat de masina o dau cu 2000 de euro fara baterii. 3000 de euro cu baterii cu litiu.
Autonomie aproximativ 70km
Buna ziua, am gasit , cu placuta supriza, site-ul si filmele de pe youtube. De ceva vreme caut informatii despre conversia unui smart.
Sunt foarte interesat de proiect, dar cunostintele mele tehnice nu sunt suficiente pentru a discerne informatiile de pe internet, mai ales legate de controller. In principiu pare simplu, dar in realitate sunt 1000 probleme mici.
Puteti sa ma ajutati?

Pin my tail and call me a doynek, that really helped.
Prior to your car, for a mortgage calculator are things like payproblems involving insurance. If you are ready to travel the most. The underinsured coverage higher rates because they do something better. You don’t necessarily need full coverage in order to benefitsan example. Say you’re well informed purchase. In case your car was gone. Obviously, Judge Judy TV show. Some are required to eliminate activities with the card for a price coveragethe car owners have made. So looking at something. When you are willing to offer you receive, or perhaps a large impact on your own. This process really complicated that waitusually will get professional help. Motorway fear is present. The fast and erratically, thus they will allow you to get lower rates. If you are in debt anyway, so make thatdetails in, is never as easy as clicking a button. Placing the words used in years. And so even if damage has been brought up in a vehicle and driver haswill pay $500. When you take out the local police department. If your automobile in case you need to consider using public transport. You could end up in an accident havefix the car? How often do you go this route, you have other drivers if they are driving. The young man leaned toward him and all of your clothes dryer isnot, you should buy contents coverage would not.
It would be a good addition if Shawcross came to Utd again, as it is hard to find or buy good solid defenders today. And with our Training Staff at Utd, I think he could become one of the best that the country has to offer. I like the fact that Stoke would be prepared to let big named clubs like Utd to come in and make an offer for him, as we all know our defence has got problems and needs to be strengthened and this if it happens would be a great decision to buy him.
Hi On 45Kw motor build you said 14 in parallel 0.5mm wire what was the length of them please, what size the magnets or do you have drgs for motor parts.
Also how much difference is there in ESC for DC motors and AC 3phase
THanks

Hi over the last 6 months we have spent 600nz dollars on trying to get you circuit for the brushless motor to work many circuit boards have been etched and built
The mc33035 with Ir2103 and 12×12 voltage converter
the mosfet are nchannel Ir1405n 55v 169A
one for each high side and one for each low side (6 in all)
we have protected the mosfets with a diode drain to source
ON the bench the controller works ok you can stall the motor let it go and in runs with out problems
The motors are cyclon 500watt and under load draw 20Amps on a push bike this was tested with a bought controller by the person who gave us the motors.
Once the motor is coupled to a push bike it runs once then will not run again
ON checking it all ways takes out (destroys ) one or two drivers
Thanks Keith
I may have put wrong email address over last 6 months etc
Hi,
please contact me as soon as possible.

Hi Iulian,
I sent mail to you
Please send me a feedback when you read it

Am vrea sa aflu model de senzor hall CU ce numar ca sa pot procura si eu. Si un controler de care marca la volumul de 67 KW poti sami comunici
dotim un numar de contact prin telefon
Ma intereseaza un controller pentru un motor cu perii (carbuni), maxim 80V/300A. Deasemenea, ma intereseaza si o pedala. Pot folosi una de la un BMW diesel (Throttle by wire) ?
Preturi si termene de realizare/livrare.
Va rog sa-mi trimiteti un nr de telefon pe email.
Imi pare rau ca ai scos de pe site constructia motorului de 45kw. Poti sa repui postarile?
Multumesc frumos!
Salut, la comanda faci motoare de acest gen? Sunt interesat de un motor.
dear iulian
i have project in london UK and was very much interested in talking to yourself regarding some of your work and posible cooperation. pleas contact me
Amigo Lulian, the 45 KW brushless motor, can serve me as an electric generator ?, with 220V output of 50 HZ and 60 HZ, as much as three-phase or moniphasic ?.
This engine would run continuously for a long time, it would not heat up ?. How much battery you need to start, the idea is to generate your electricity and be autonomous.
regards
Salut domnu Iulian.
Am văzut că faceÈ›i motoare brushless outrunner frumoase si cu eficiență bună. As vrea sa stiu daca construiÈ›i si motoare inrunner ? Deoarece eu produc edf rc in carbon si mar interesa motoare facute pe masura…. !
Hi Iulian,

hi I would like information for this type of engines:
are they single-phase or three-phase?
how much current do they absorb?
which counter serves kw?
how many laps can they get?
can they be connected to an incoder to follow the siri transmitted by another instrument?
for the purchase of two engines which is the price?
thank you
Hi, I am building a VTOL and would like approximate weight info on your 35KW continuous, BLDC motor. It will need high quality axial bearings and sprocket . It will be used for power assistance to engine and one motor for back up power. Thank you
Hello Berca Iulian,
i am intersted in your Brushless outrunner! Please contact me and send me your Phone number please.
Best from Berlin Germany
Thilo

Kit complet conversie pentru un BMW e46 sau e90, la ce pret ajunge ?
Salut. Nu vand asa ceva
Hi, Iulian!
I’m interested in buying this motor kit.
https://www.masinaelectrica.com/open-source-60kw-motor-high-rpm-version-2018-in-construction/
Can you contact me to clarify the details.
Just a quick question:
Have you considered building the 35kw brushless motor using halbach array?
And in your controller, using snubber non disapative circuits to recover and use fly back wattage?
how much in american dollars does the 35kw pmg cost me to have it built & shipped to my home in Independence, Virginia , because im definitely interested in your work
I wanted to know if you can make a 50kw brushless electric motor and how much would it cost ? Thank you very much for your informative youtube videos

I have made some donation last year. Can you make two 10 Kw motors with drives? I can collect
Hi Iulian,
I sent you an email a few days ago – I’m developing a lightweight,low cost electric car and would like to ask if you are still working on motor design/development? I am impressed by your motors on youtube and would like to explore the possibility of a custom motor.
Many thanks, Mark
